Carbonaceous quantum dots (CQDs) are carbon nanomaterials offering
significant contributions in the fields of sensing, biosensing, optoelectronics, and
energy storage. CQDs materials with edge defects are suitable candidates for LED
emitters, water splitting, optoelectronic and photodetectors devices. The role of
attached functional groups and edge effects on flexible energy storage devices is
discussed in this chapter. The future prospects and underlying challenges for CQD-based material for wastewater remediation, in addition to factors such as their
sustainability, durability, performance and economics in the context of industrial scale-up, have also been explored in this chapter
Keywords: Carbon dots, Energy devices, Photodetectors, Quantum dots, Wastewater remediation.
